N64 Super Mario 64 (USA) "16 stars" in 15:24.08 by Rikku
Ever wonder if Mario was actually a ninja wearing blue overalls? Now you know.
This run completes the game after collecting a mere 16 stars. It was originally intended that the player collect a minimum of 70 to finish, but a few bugs allow Mario to pass through doors and barriers that require a minimum number of stars to open. This is also used when unlocking a door would take longer than setting up and executing the bug.
Mario has a very wide range of skills for mobility and some of the physics of this game are easily abused by an experienced player.
This 10-second improvement is half made of no saving and a different overworld route, and half of just framewise optimizations. It was arrived into by AKA (now known as Mitjitsu) and Rikku together.
